Embodiment
At first; With reference to Fig. 1-3, can see a kind of device 1 that is used to handle nuclear fuel bundle (not shown), as will being described in detail subsequently; This device 1 has voussoir 2 especially; By means of instrument according to the present invention, this voussoir 2 can be crimped in the point element that gets into this device 1 through pressure, and can be drawn out of through with pressure from then on it being evicted from similar elements.
Generally speaking, this operating control 1 is traditional and is to know for those skilled in the art.For this reason, the explanation that regards to this device under will be concise and to the point.
As shown in figs. 1 and 3; Mechanical type tulip shape part 10 has head 18 in its end, and these heads 18 are by spaced apart circumferentially, and outwards wants and lock 12 and contact; Lock has formed the outer radial supporter that is used for this head, thereby allows these heads radially inwardly to be pushed back.As indication, in Fig. 1, install in a kind of state of 1 sd so, that is, the head 18 that is radially inwardly pushed back fully allows to place protection gag 22, and this protection gag is used to protect especially its clamping head 18 of pawl 4.Yes is in the state of not adopted between the operating period at operating control 1 for this state.
In such device; Can be adjusted along the relative positioning of direction 16 between lock 12 and the mechanical type tulip shape part 10; It only is on its nominal position, to be unfolded at the most that mechanical type tulip shape part 10 is designed to make its head 18; Just when they are not exerted pressure by lock 12, as shown in Figure 3.Therefore; As mention in the above, the lock 12 that is set at just on the tulip shape part outside allows the head 18 of expansion to be pushed back, and the design that is kept is actually such; That is, the amplitude of head 18 expansion is directly related with respect to the location between the tulip shape part with lock.
In addition; Head 18 is by 24 supportings of tulip shape part bar, and this tulip shape part bar 24 is provided with along longitudinal axis 14, and the opposite end of that end with supporting head 18 of bar 24 has screw thread 26; To be used for the installation of bar 24 on inner cylinder 28, this inner cylinder 28 extends to controller 8 always.
In order during the relative motion of direction of actuation 16, to provide lock 12 to be relevant to the guiding of tulip shape part 10 between these parts; Will be in the through hole 30 of tulip shape part bar 24 crimping voussoir 2; This hole 30 has oval in shape excellently; As shown in clearer among Fig. 3, and this hole 30 is manufactured into the axis 32 along the longitudinal axis that is orthogonal to this device 14.
In addition; Voussoir 2 with the elliptical shape that is matched with through hole 30 shapes basically has two ends; Protrude on each side of tulip shape part bar 24 respectively these two ends; And be slidably mounted in two relative slotted eyes 34 along direction of actuation 16, these two slotted eyes 34 are formed on respectively on the tulip shape part lock 12.Nature; For the bar 24 that allows supporting wedges 12 regularly and with the lock 12 that matches in the voussoir end between relative displacement; Slotted eye 34 has the longitudinal size bigger than ellipse hole 30 along direction 16; Should be appreciated that these slotted eyes 34 also are manufactured into through hole on the lock 10 with pipe or hull shape shape.
Therefore, Fig. 4 is illustrated in tulip shape part 10 and locks between 12 during the relative motion of direction of actuation 16 (purpose is to take more lock near controller 8 position), can see that head 18 is discharged gradually, and this head is on the stop position that their launch.So; In this configuration; At tulip shape part 10 with before locking the relative motion of carrying out between 12 on the reverse direction once more; Can between head 18 and end 36, introduce and be used to connect nuclear fuel bundle 38, this rightabout relative motion is intended to move lock away from controller 8, and purpose is radially to push back head 18 inwardly and apply enough keep-uping pressure on the connection end 36 of nuclear fuel bundle 38 until these heads 18 through locking 12; Thereby the nuclear fuel bundle is fully remained on the operating control 1, and is such as shown in Figure 5.
Then, nuclear fuel bundle 38 can be handled by device 1, for example is used for guaranteeing that it is from framework extraction or its introducing framework.
Now will be with reference to Fig. 6-8 descriptive tool 40; This is the object of the invention place; This instrument be configured to be used for alternately guarantee voussoir 2 through pressure crimping in tulip shape part bar 24, thereby and make this voussoir 24 from bar, be drawn out of through it being evicted from pressure.
About the extraction operation of evicting from of carrying out through pressure, extraction can be carried out during the attended operation that need mechanical type tulip shape part 10 and lock 12 be disassembled.In fact, the tulip shape part 10 that is installed on the inner cylinder 28 through screw thread 26 of outwarding winding can be only be implemented after voussoir 2 being removed from its hole 30.
In addition, again through tulip shape part 10 is screwed into assemble tulip shape part 10 on the inner cylinder 28 after, and then after the dismounting of mechanical type tulip shape part 10 and lock 12, the pressure crimping operation can be performed during these identical attended operations.In addition, this crimping operation also should be performed during the new operating control of assembling.
Generally speaking, it is divided into two relative parts with respect to vertical plane, and first 48 is exclusively used in pressure crimping, and second portion 50 then is exclusively used in through pressure and evicts from.At this on the one hand, come to select fast to be suitable for the part of associative operation in order to allow the user, and any risk of making mistakes can not occur, be provided with on each that will be in these parts 48,50 and clearly indicate for example " crimping " and " evicting from ".
Therefore, for first 48, first socket 52 that is used for pawl 4 is fabricated on pedestal 44, and this socket 52 for example has semi-circular cross-section, and its form fit is just locked 12 external surface shape in the outer shape of pawl 4, as shown in clearer among Fig. 7.The aperture of this socket 52 is directed by upwards, and just the stayed surface 54 with pedestal is opposite, and pedestal will for example rest on the support member that is known as " broaching machine " on this stayed surface.
The pressure crimping head 56 that will cooperate with voussoir 2 is established with this socket 52 relatively; This crimping head 56 is installed on the head holder 46 along first glide direction 58 movably; This first glide direction 58 preferably is parallel to vertical direction; And therefore be orthogonal to horizontal direction, in the operating period of crimping voussoir 2, pawl 4 will rest in the socket 52 in a horizontal direction.
Should be pointed out that crimping head 56 has the shape of well known to a person skilled in the art generally, have the crimping drift 60 that will contact especially in its end with voussoir 2.In Fig. 6, can see that crimping head 56 is held and rests on the higher position, and drift 60 does not touch voussoir, does not contact any other element yet.This function that preferably adopts can be for example by means of being arranged in the Flexible Reset device (not shown) between head holder 46 and the crimping head 56 or realizing by means of suitable adjustment.In this case, can be so that left free space enough be used for through pawl is inserted socket 52 and flatly introduces pawl 4 along its longitudinal axis 14 below drift 60.
Shown in Fig. 6-8, crimping head 56 has meeting device 62, for example has the shoulder shape, its objective is to be limited in during the crimping crimping head with respect to the stroke of main body 42.By this way, crimp stroke can be limited with respect to the geometric configuration of instrument 40 and pawl 4 in advance, can reduce the risk of damaging pawl like this.In fact, when shoulder 62 is resisted against 46 last times of head holder in stroke end, the operator is advantageously informed, and crimping operation accomplishes, and under any circumstance can not apply any extra pressure again on voussoir 2.
Shown in clearer among Fig. 7, crimping head 56 is contained in first of head holder 46 to be run through in the housing 66, and through this housing, therefore crimping head 56 can slide along first direction 58.Preferably; The geometric configuration of slipper that can make geometric configuration that the housing 66 of winning adopted and crimping head 56 is only when housing 66 is in single and predetermined orientation with respect to head holder 46; Just allow head holder to get in its relevant hole, this has guaranteed that advantageously crimping drift 60 is with respect to main body 42 and therefore with respect to the suitable location with the voussoir that is crimped 2.Therefore the risk of pawl 4 significantly reduces during the crimping of voussoir 2.
